9.Nowadays,cell phones are part of our lives.Many people have cell phones.They can help us easily find people anywhere at any time.However,using cell phones too often may cause cancer(癌癥).It's reported that people who use a cell phone for 10years or more may get brain cancer.
The suggestions below may help you reduce(減少) the risk of cancer:
When using your cell phone,try to keep it away from your body as much as possible.Don't put it on the bedside table when you go to sleep.
When you're on the cell phone,use the speaker(揚(yáng)聲器).In this way,you have just 1/100th of the contact(接觸) with radiation you have when you hold it to your ear.An earphone is also a good idea.
Try to keep your conversations short.If you need to talk longer,use an ordinary phone instead.
Change ears when you're using your cell phone.Before putting it to your ear,wait until the person you are calling picks up the phone.
Your phone gives out radiation when you talk or send messages,but not when you're listening or getting messages.Listening more and talking less can lower the risk of cancer.
Do not use your cell phone when the signal(信號(hào)) is weak or when moving at a high speed,for example in a car or on a train.At high speeds your phone is trying to pick up signals,and this increases the radiation it gives out.

51.According to the text,using cell phones too much may causeB.
A.toothache            
B.cancer            
C.heart disease
52.The underlined word"radiation"in Paragraph 4probably means"A"in Chinese.
A.輻射              
B.電池              
C.網(wǎng)絡(luò)
53.You'd betterC.
A.use your cell phone when the signal is weak
B.use your cell phone on a high-speed train
C.change ears when you're using your cell phone
54.Which of the following is TRUE according to the text?A
A.Using an earphone is a good way to reduce the radiation.
B.You can put your cell phone on the bedside table when you go to sleep.
C.Listening less and talking more can lower the risk of cancer.

A.buy a cell phone        
B.use a cell phone         
C.repair a cell phone.

4.Have you ever dreamed about sending a letter to yourself or your friends in the future?While express mail(快遞) is a fast way to send your letters,there is another type of mail appearing in China as a new business-future mail.
"The letter should be sent next Mother's Day and not a day earlier!"Lin Xiaofan,a college student in Shanghai,tells one of the companies offering the service.

Zheng said customers are glad to sign a contract(簽訂合同) to make sure that they can be  compensated if their letters are lost or damaged.
Most of the customers are college students and young white-collar(白領(lǐng)) workers.Psychologists (心理學(xué)家) said that young Chinese might have a new way to express their feelings through this service.Most people put their hopes and wishes in the letter so that they can experience the connection(聯(lián)系) between the past and the present when they receive the letter.
